idea热部署不起效果

1.添加依赖

  <!--devtools热部署-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-devtools</artifactId>
            <scope>runtime</scope>
            <optional>true</optional>
        </dependency>

2.开启热部署

<build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <fork>true</fork> //必须添加
                    <addResources>true</addResources>
                </configuration>
            </plugin>
        </plugins>
    </build>
